UEFI0252


Message: 

Unable to boot a boot option because the watchdog timer has expired.System will reset.


Detailed Description: 

The watchdog timer is armed before the BIOS boot manager invokes an UEFI boot option. The watchdog is set to a period of 5 minutes. The Operating System boot loader from the boot option is required to disable the watchdog timer after it is successfully loaded, otherwise the system will reset if the timer expires.


Recommended Response Action:

Check the boot option image and boot loader. Update them to the latest version if possible.
 

Cause

The watchdog timer expired, causing the server to reset.

  • The watchdog timer is armed before the BIOS boot manager invokes an UEFI boot option.
  • The watchdog is set to a period of 5 minutes.
  • The Operating System boot loader from the boot option is required to disable the watchdog timer after it is successfully loaded.
Caution: The watchdog timer expiration can cause the server to reset, resulting in data loss or corruption.
